Also called sensitive dentin, dentin sensitivity, dentin hypersensitivity, cervical sensitivity, cervical hypersensitivity.
Sensitive teeth, also called dentin hypersensitivity is a very common dental condition where a sharp but short duration pain occurs in the dental region inside the teeth and gums in response to certain stimuli but not caused due to any other disease. The stimuli can be thermal, mechanical or tactile, electrical, osmotic, or due to chemicals or evaporation.
The root cause of dental hypersensitivity is exposure of the dentine layer of the teeth that lies just underneath the outer enamel coating. The dentine layer may be exposed due to receding gums, or due to the erosion of the enamel. Dentine contains millions of microscopic tubules fanning outward from the pulp. These dentinal tubules are filled with a fluid. Once exposed, the external stimuli cause changes in the flow of this fluid, and this triggers the sudden sharp pain response from the mechanoreceptors from the nerves in the pulp. Some level of sensitivity is noted even in healthy teeth, but the response is much sharper and more intense in case of hypersensitivity.
A great number of treatment options are available to treat and manage dental hypersensitivity. Even without treatment hypersensitivity response is slowly managed and muted by the body by laying down tertiary drains and thickening the dentine, but these processes take a very long time, and the condition might turn more severe if the pulp becomes involved and inflamed.
A multitude of treatment options are available for dental hypersensitivity. The most easily available are desensitizing toothpastes that are available over the counter at any pharmacy. These toothpastes help to block pain by forming a layer over the exposed ends of the dentinal microtubules. Fluoride is also used to strengthen the enamel so that it resists decay. The exposed dentin surface may also be sealed in a process similar to dental filling for cavities. Lost gum tissues may need to be replaced by taking up tissues from elsewhere in the mouth. In case other treatments are ineffective, a root canal procedure is performed, which involves a surgical removal of pulp with all its nerve endings. The procedure is usually applied to treat severe hypersensitivity problems arising from other more severe causes like inflammation of the dental pulp. Treatments may need to be combined with teeth crowns to protect them from further damage.
Dental hypersensitivity is characterized by sharp sudden pains in the teeth in response to various stimuli. Commonest of these stimuli is temperature, where the pain is triggered by cold or hot liquids coming in contact with the affected teeth. Even cold air can cause a dental hypersensitivity in some of the more severe cases. Brushing teeth may cause the pain. Sugar solutions like fruit juices, soft drinks, etc. can cause the pain to occur. Solid or liquid edibles with acidic pH coming in contact with the affected teeth can cause pain. Dental hypersensitivity may occur due to some other dental diseases, in which case the underlying cause needs to be addressed. If no other diseases are seen to be the cause of hypersensitivity, the patient is eligible for hypersensitivity treatment.
Some dental diseases like pulp inflammation may be the cause of hypersensitivity. In this case, treatments like sealing of dentine is not advised as the pulp may turn necrotic and the damage may spread to other parts of the mouth and gums.
Some side effects are associated with treatments for sensitive teeth. For example, fluoride treatment can cause fluoride poisoning if used non-judiciously. Dental crowns placed to protect the enamel from decay may further aggravate the problem of increasing dentinal hypersensitivity.
Post treatment guidelines for teeth hypersensitivity include simple habits to keep the teeth and gums clean and healthy to prevent their further decay. These include regular brushing and flossing at least twice a day, rinsing out the mouth properly after every meal, having some water after having some acidic food, wearing mouth guards if grinding teeth is a regular problem, etc.
Some of the treatment options manage the condition by preventing further enamel decay and reducing dental sensitivity, and these treatments are regular treatments. Root canal surgery is performed in severe cases, and it takes about three to four weeks to recover.
Treatment costs for dental hypersensitivity vary widely from Rs. 50 going up to Rs. 10,000 or higher for surgical procedures and follow ups.
Some treatments are regular and ongoing. Results of most treatments are long lasting if proper care is taken and further decay does not occur. Results of root canal surgery are permanent since the entire pulp with nerves is removed.
Rs. 50 - Rs. 10,000
Tooth sensitivity is tooth discomfort in one or more teeth that is triggered by hot, cold, sweet or sour foods and drinks, or even by breathing cold air. The pain can be sharp, sudden, and shoot deep into the nerve endings of your teeth.
What Causes Tooth Sensitivity?
Tooth sensitivity occurs when the underlying layer of your teeth - the dentin - becomes exposed as a result of receding gum tissue (the protective blanket that covers the tooth roots). The roots, which are not covered by hard enamel, contain thousands of tiny tubules leading to the tooth's never center (the pulp). These dentinal tubules (or channels) allow the stimuli - for example, the hot, cold, or sweet food - to reach the nerve in your tooth, which results in the pain you feel.
There are many factors that may lead to the development of tooth sensitivity, including.
Brushing too hard. Over time, brushing too hard or using a hard-bristled toothbrush can wear down enamel and cause the dentin to be exposed. It can also cause recession of the gums (the gum tissue pulls away from the teeth).
Plaque build-up. The presence of plaque on the root surfaces can cause sensitivity.
Mouthwash use. Long-term use of some mouthwashes. Some over-the-counter mouthwashes contain acids that can worsen tooth sensitivity if you have exposed dentin (the middle layer of the tooth). The acids further damage the dentin layer of the tooth. If you have dentin sensitivity, ask your dentist about the use of a neutral fluoride solution.
Recent routine dental procedures. Sensitivity can occur following teeth cleaning, root planing, crown placement, and tooth restoration. Sensitivity caused by dental procedures is temporary, usually disappearing in 4 to 6 weeks.
What Can I Do to Reduce Tooth Sensitivity?
Maintain good oral hygiene. Continue to follow proper brushing and flossing techniques to thoroughly clean all parts of your teeth and mouth.
If you still have discomfort, talk to your dentist. There may be some dental procedures that may help reduce sensitivity, including the use of.
Many adults suffer from Periodontal disease, which may result in slight swelling of the gums or something more severe as grave damage to the bone and tissue, which holds on to the teeth. After the onset of Periodontal disease, dental care is essential as it will determine the progress of the condition.

Sensitivity of the teeth can be because of multiple reasons:
1) Too hard brushing or brushing your teeth with a hard brush can wear off the proctective layer of your teeth called the enamel which can lead to sensitivity.
2) Rubbing of acidic food , baking soda etc can wear off the enamel.
3) Drinking Aerated drinks on regular basis.
4) Conditions like hard clenching or bruxism
The gums are also called the periodontium - perio for around and dontium for tooth as the gums are literally present "around the tooth." There is a softer mucosal portion that runs along the tooth in a curved manner and a stronger fibrous portion that connects the tooth to the jaw bone. Together, they provide the structural support for the tooth to be held in place. In addition, they also have an esthetic value with the healthy pink color. The mouth has the largest number of bacteria in the body, which act on the food debris that is present on the tooth and the gums. This causes infection in both the gums and the tooth.
Types: Periodontal disease can be localized or general.
Symptoms: In both the cases, the following symptoms:
Management and Prevention:
Gum disease is very easy to identify and can be completely cured.
